Radioactive Decay
It is spontaneous process because it is not affected by any external factors such as temperature or pressure
It is a random process in that it cannot be predicted which nucleus will decay next

Half-life
Half life of a radioactive nuclide is the time taken
Decay constant
It is the probability per unit time of the decay of a nucleus
Activity
It is the number of nuclear decays occurring per unit time in the source
It is measured in becquerels (Bq)

Nuclear fission
It is the splitting of a heavy nucleus into two lighter nuclei of approximately the same mass
Nuclear fusion
It occurs when two light nuclei combined to form a nucleus of greater mass
